Because elite isn’t a moment - it’s how you fuel between them

You demand world-class performance - but your nutrition system isn’t built to deliver it. Without precision fuelling, recovery, and consistency, even the most talented athletes and performers fall short. Energy dips, injuries creep in, and results become unpredictable. This isn’t a training problem. It’s a systems problem. And the cost? Missed opportunities, delayed progress, and potential left on the table.

I’ve made big strides, not just the obvious stuff where you need to rehab the injury, but I feel like I’m coming back in a lot better shape in all aspects as a better athlete to be honest.

Man lifting a barbell at the training gym at King Perfomance Ideology

KPI for me has not only made me feel better physically but also mentally. Going there every week makes me feel really confident in my play at my club on a diffrent level. I’ve gotten more flexible, stronger, faster and better with my feet since being at KPI i recommend people go there if there dedicated on getting better for themselves

A young man training on the field at King Perfomance Ideology

Worked with Tom and his team for a number of years now and every season the attention to detail seems to get better and better. Always working to get me in the best possible shape for the season ahead and continue the work throughout the competitive season.

Really good. The improvements you get in such a small time as long as you trust and stay consistent is great. I’m now on top of the stat boards which was never really a thing for me so really happy.

I’ve been working with Tom for almost 2 months now and throughout this time already I am starting to see the rewards not only off the pitch in the gym but on the pitch in my every day training schedule at the club. His attention to detail is spot on and the time and effort he puts in with his clients couldn’t be better.

Man on the treadmill at the training gym at King Perfomance Ideology

I really enjoyed working with Tom during the off season, his knowledge is top class and he is always looking to improve which is a big reason why I worked with him. He was very specific with our work and after thorough examination came up with a great training programme on and off the pitch for me to get me in good shape for the new season...
